y = 4+e^-x/3
y-4 = e^-x/3
ln(y-4) = -x/3
x = -3ln(y-4)
so, f inverse = -3ln(x-4)
for domain, recall that ln(u) is defined only for u>0
domain for exponentials and range for logs is all reals
Find the inverse of the following function. Find the domain, range, and asymptotes of each function.
Graph both functions on the same coordinate plane
-x/3
f(x)=4+e
( if this makes sense, not sure how else to show it. the -x/3 is after the e like -x/3 to the power of e)
please help me! show steps also, if i an just given an answer that wont help me! thanks in advance!!!
